Product details
Overview
The MAX16005DTE+ from Maxim Integrated is a low-voltage, hex-voltage microprocessor supervisor IC in a 16-pin TSSOP package, monitoring six independent supply rails (VIN1–VIN6) with fixed and adjustable thresholds, featuring an independent watchdog output (WDO), reference output (REF = 1.235V), and open-drain RESET with 140ms min timeout. It serves multivoltage ASICs and server power sequencing.
For engineers reviewing the MAX16005DTE+ datasheet, MAX16005DTE+ pinout, MAX16005DTE+ application, or MAX16005DTE+ equivalent, key selection considerations include its 6-channel supervision capability, independent WDO for fault isolation, REF output accuracy (±0.035V), TSSOP-16 thermal performance (754mW at +70°C), and -40°C to +125°C operation.
Technical Context
The MAX16005DTE+ implements a dual-path supervision architecture: one path drives RESET low when any monitored voltage (VIN1–VIN6) falls below its threshold or MR is asserted, with reset timeout programmable via SRT capacitor or fixed at ≥140ms; the second path provides independent WDO assertion on watchdog timeout (1.6s typ) without startup delay-unlike MAX16001/2/4/6/7.
It integrates a precision 1.235V reference (±0.035V over temp) sourcing up to 40µA, six open-drain outputs (OUT1–OUT6) with internal 30µA pullups, and digital control inputs (TOL for 5%/10% threshold tolerance, MARGIN for simultaneous output deassertion, and WDI for watchdog edge detection).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supervised Channels | 6 independent voltage inputs (VIN1–VIN6), configurable with fixed (e.g., 3.3V, 2.5V, 1.8V) or adjustable (≥0.4V) thresholds |
| RESET Timeout | ≥140ms minimum (SRT = VCC); adjustable up to ~3.92ms with 1500pF capacitor; ensures reliable system boot hold-off |
| Watchdog Output | Independent WDO pin (not shared with RESET); asserts low on 1.6s timeout; no 54s startup delay-enables immediate post-reset monitoring |
| Reference Output | 1.235V ±0.035V (0–40µA load); stable over -40°C to +125°C; usable for ADC reference or margin testing calibration |
| Supply Range | VCC = 1.0V to 5.5V; guaranteed correct logic state down to VCC = 1V-supports ultra-low-voltage brownout detection |
| Package & Temp | 16-pin TSSOP (5mm × 4.4mm); rated for -40°C to +125°C industrial/automotive ambient operation |
| Quiescent Current | 45–70µA (VCC = 2.0–5.5V); enables always-on supervision in power-constrained systems |

| 3, 4, 5, 6, 7, 12, 14, 16 | GND, VCC, MR, MARGIN, TOL, SRT, WDI, RESET | Ground reference, unmonitored VCC input, active-low manual reset, margin disable, threshold tolerance select, reset timeout set, watchdog input, and active-low system reset output |
| 8, 9 | WDO, REF | Independent watchdog output (open-drain, 1.6s timeout) and precision 1.235V reference output (40µA max sink) |
Key Features
| Feature | Design Value |
|---|---|
| Independent WDO output | Enables dedicated watchdog signaling without interfering with main RESET line-critical for fault-isolated diagnostics in servers |
| 1.235V reference with ±0.035V accuracy | Provides stable, traceable voltage reference for margin testing or ADC calibration without external components |
| Capacitor-adjustable reset timeout | Supports precise timing tuning (200µs to ~3.9ms) via SRT capacitor-avoids fixed-timer limitations in diverse boot sequences |
| Internal 30µA pullups on all open-drain outputs | Eliminates need for 6 external pullup resistors, reducing BOM count and PCB area in dense multivoltage systems |
| Guaranteed operation down to VCC = 1V | Ensures valid logic states during deep brownout conditions-improves robustness in unstable power environments |
Applications
| Storage Equipment | Servers |
|---|---|

IC Role / Device Role / Timing Role: Provides six-channel voltage monitoring with independent OUTx outputs for per-rail fault reporting and unified RESET for system-wide reset coordination. Use Value: Enables granular power-fail diagnostics while maintaining deterministic boot timing via 140ms+ RESET timeout. |
| Networking Equipment | Multivoltage ASICs |
Use Scenario: Ensuring clean power-up of 100G optical transceiver modules with mixed 3.3V, 2.5V, 1.8V, and 1.2V supplies. IC Role / Device Role / Timing Role: Supervises six rails using factory-configured thresholds (MAX16005D variant); REF output calibrates laser bias DACs. Use Value: Guarantees optical module interoperability by meeting strict power-sequence compliance (e.g., SFF-8472) and reduces calibration drift. | Use Scenario: Power sequencing and health monitoring for AI accelerator ASICs requiring 12 rails-where MAX16005DTE+ supervises critical subsets (e.g., VDD_CORE, VDD_MEM, VDD_IO, VDD_AUX, VDD_PLL, VDD_MGMT). IC Role / Device Role / Timing Role: Acts as primary supervisor for high-priority rails; MARGIN input disables all outputs during production voltage margining tests.

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervision applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16005ATE+ | TQFN-16 (4mm × 4mm) vs. TSSOP-16; identical electrical specs; 1349mW power dissipation rating vs. 754mW | Better thermal performance in space-constrained layouts; requires different land pattern (90-0070 vs. 90-0117) | Select MAX16005ATE+ for high-density boards needing lower junction-to-ambient θJA; choose MAX16005DTE+ for legacy TSSOP footprints or cost-sensitive volume builds. |
| TPS3808G33DBVR | Single-supply supervisor (3.3V only); no WDO or REF output; 200ms fixed timeout; SOT-23-6 package | Lacks multi-rail capability, watchdog independence, and reference functionality-suitable only for simple single-rail monitoring | Use only if supervising one rail with no diagnostic or calibration requirements; not a functional substitute for MAX16005DTE+ in hex-rail systems. |
Compared with MAX16005ATE+, the MAX16005DTE+ trades thermal headroom for board-level compatibility and lower assembly cost; versus TPS3808G33DBVR, it delivers six-fold supervision depth, independent fault signaling, and metrology-grade reference capability-making it irreplaceable in complex multivoltage platforms.

FAQ
What is the function of the REF pin on the MAX16005DTE+?
The REF pin on the MAX16005DTE+ delivers a precision 1.235V output with ±0.035V accuracy over -40°C to +125°C and can source up to 40µA. It is used for calibration reference in margin testing or as a stable ADC reference-distinct from the RESET and WDO outputs and not present on other MAX16000-series variants except MAX16005.
Does the MAX16005DTE+ have a watchdog timer startup delay?
No, the MAX16005DTE+ watchdog timer has no startup delay-unlike MAX16001/2/4/6/7 which require 54s before first timeout. The MAX16005DTE+ begins counting immediately after reset timeout completion, enabling rapid fault detection in time-critical applications like network switch failover.
How many voltage rails does the MAX16005DTE+ monitor, and what threshold options are available?
The MAX16005DTE+ monitors six voltage rails (VIN1–VIN6). Thresholds are configurable per the MAX16005D variant: VIN1 = adjustable, VIN2 = 2.5V, VIN3 = adjustable, VIN4 = 1.8V, VIN5 = adjustable, VIN6 = adjustable. TOL pin selects 5% or 10% tolerance, and fixed thresholds include 5V, 3.3V, 3V, 2.5V, 1.8V, 1.5V, 1.2V, and 0.9V.
What is the purpose of the MARGIN pin on the MAX16005DTE+?
The MARGIN pin on the MAX16005DTE+ is an active-low input that deasserts all outputs (OUT1–OUT6, RESET, WDO) when pulled low-forcing them into high-impedance or high state regardless of input voltage conditions. This enables safe voltage margin testing during production without triggering false resets.
Can the reset timeout period of the MAX16005DTE+ be adjusted, and how?
Yes, the reset timeout period of the MAX16005DTE+ is adjustable via an external capacitor on the SRT pin. Connecting SRT to VCC sets a minimum timeout of 140ms; connecting a capacitor (e.g., 1500pF) between SRT and GND extends it to ~3.92ms. The relationship is tRP = 2.06 × 10⁶ × CSRT, validated across temperature and supply voltage.
